My invention is a thread-dressing machine;

" iandit consists of the novel constnuction and lcombinationo'f. the severalv parta-:asfhcreinp i :after particularly described, and'spfecitically Esetforth in theclaimsf f 1 Theobjectof my invention is jtoprpvide a com pact machine which iScapahle of sizing, drying, andV polishing the 'thread while it is twisting aud'at the same time'greatly increasing tliejpr'oduct ofsufchmachines. f

In the drawings, 1 represents,the'framefof ;the machine l to supportthe operating! parts.

In proper hearings are inountedtliej )uri1a`ls of three pulleysy 2, 3, andV 4.1' A bfelt ,from ,the pulley 2 drives thefpulleyf 6,' '-properly mounted on ahracket from theframe 1. A blt A7' from the p ulley l,2 ,drive'sltheL pulley 8 fouone end ofthe brush-cylinder," auda cross- ,belt 9 from a pulleyin linewith the pulley 2 on 'thesameshaftidrives a pulley Sakofthej'brushcylinder on the shaft of'saidbrusheylinder at lthe opposite end thereof.-`. A belt 1Q vfrom the pulley '3 drives .the pulley p 1110i' .thfe lower ironing-cylinder, and across-belt 1 21from a pulley in line with thepulleyonjithe same shaft drives a pulley 11L o ftheironing-cylinder onthe shaft of said lower ironing-cylinder atthe opposite end thereof; A belt 13 from "the pulley 4 drives'thepuflley 14of the upper' ironing-cylinder, andga ,cross-belt l5 from a pulley 16 in line with the pulley 4 on the sameishaft drives a pulley 17 of the'upper ironing-cylinder att-hc opposite endthereof.'

Onthe upper shaft concentric `with the pulley 4is a pulley 18, and a'belt 19 from thepullrey 18 drives a. pulley 42O, which is mounted'A ou a standard 2l at thetop ofthe machine? The thread jto'be glazed and`Y` polished byA my said machine is'wound on-V spools or bobbins 22, which are mounted, respectively, on spindles 23.

On each side of the machine is a trough 24, containing a suitable sizing liquid; On the front of each trough 24 is a bracket 25, supporting a rod 26, and the thread unwound IOO from the spool 22 passes over said rod 26 down into the said liquid. In each trough 24 is pivotally mounted on a rod 27 a lever 2S, having its upper end above the upper edge of said trough and slightly bent and flattened, as shown, and provided at its lower bent end with a peripherally-grooved wheel 29, around the under side of which the thread 30 passes, as best shown in Fig. 10. This 1ever 2S and its connected parts are fully shown in the enlarged detail views of Figs. 26, 27, and 28, where it is seen that said lever 2S has a hub 31, by which it is mounted loosely on the rod 27. A collar 32 is held on the rod 27 by a set-screw and serves to prevent lateral movement of the hub 3l, which abuts said collar 32. A collar 34 is mounted on the rod 27 and abuts the hub 31 on the opposite side. The collar 34 is held in position by the set-screw 35, and said collar has a projection of less diameter which enters the contiguous open end of the hub 31. A spiral spring 36 is in a concentric chamber of the hub 31 and has one end thereof in contact with the end of the projection of the collar 34 and the other end in contact with an internal shoulder in the hub 31. There is a Wedge-shaped projection 37 from the side of the collar 32, and the saine enters a slot on the adjacent edge of the hub 31 as the lever 2S is turned, thus locking the parts together when in the position illustrated in Figs. 10 and 27.

The thread after it has been saturated in the sizing liquid of the trough 24 passes up through the lower twisting mechanism, and this mechanism is thrown into and out of operation by a shipper and gearing, which I will now describe. This twisting device is shown in Figs. 7, S, 9, 10, 11, 13 to 1S, inclusive. On a rod or shaft 39 is mounted the pulley 6. On a bracket 40, bolted at 41 to the frame 1, is a vertical tubular bearing 42, in which is rotatably mounted a shaft 43. A gear 44 and beveled gear 45 in one piece are mounted on the shaft 43. A shipping-lever 46 is pivotally mounted at 47 upon the bottom of a stand 4S, which extends down from the bracket 40. A fixed collar 49 is secured in place upon the shaft 39 by the set-screw 50. A beveled gear 52 is slidably mounted on the shaft 39 and has a hub 53 with a peripheral groove in which the shipping-lever 46 is supported. The beveled gear 52 is movable by the shipping-lever 46 into and out of engagement with the beveled gear 45. The beveled gear 52, though slidable on the shaft 39, is splined or otherwise secured thereto,

so as to revolve with it; but when the bev-- eled gear 52 is by the shipping-lever 46 moved out of engagement with the beveled gear 45 the latter does not revolve; but when the beveled gear 52 is moved by the shipping-lever 46 into engagement withthe beveled gear/4.5 the latter is revolved. The revolution of the beveled gear 45 causes the gear 44, which-is integral therewith, to revolve also, and the Vgear 44 by engagement with the gears 54 and 55 causes the revolution of the gears 56, 57, 5S, 59, and 60, which are in mesh with said gears 54 and 55. The result of this arrangement is that the gears 45, 56, 57, 58, 59, and (50 all rotate in the same direction, as indicated by the arrows thereon in Fig. S.

Each one of the gears 56, 57, 5S, 59, and 60 operates a twister, said five twisters being arranged in a series, as seen in Figs.` 1, 7, 10, and 13. In Figs. 14 to 18, inclusive, are shown enlarged detail views of each twister.

On the bracket 40 is mounted a fixed beveled gear 6l. A vertical shaft 62 has a concentric circular disk 63, by which it is supported upon the upper plane surface of the fixed beveled gear (il. The shaft G2 extends down through a tubular bearing 64 of the bracket 40 and has at its bottom a gear, (one of those designated as 56, 57, 5S, 59, and 60, say, in Figs. 14, 15, and 16.) This gear is designated as 5G.

Two standards or uprights 65, integral with the disk 63, extend up therefrom. These standards are slotted, as indicated in Fig. 15, and have bearings in which is mounted the shaft 66 of the beveled gear 67, which meshes with the fixed beveled gear 61. A. set-screw 68 through the hub 69 of the beveled gear 67 fastens it to the shaft 66. A roller 70 is fastened on the shaft 66. A roller 71, fastened on a journal 72, is rotatably mounted in the slots of the standards 64 65 and rotates by its frictional contact with the roller 70. A block 73 fits into these slots to close the outer opening thereof and is held in place by the set-screws 74 75. A cappiece 76, having a central flaring opening 77, is fastened by screws 78 to the tops of the standards 65.

The fixed beveled gear 61 has a hub 79, and a set-screw S0, passing through the hub 79, secures it in place upon the shaft 62. The lower portion of the tubular bearing 64 below the bracket 40 has a horizontal slot or opening 81, as shown in Fig. 14. A sleeve or tube 82 loosely surrounds the shaft 62, Figs. l5, 16, 1S, and is provided with a handle S3, which projects out through the radial slot or opening 81. The sleeve S2 has a longitudinal slot 84. The vertical shaft 62 has a longitudinal slot S5. The gear 56, tubular bearing 64, hub'79, beveled gear 6l, and disk 63 have each a radial slot, as illustrated in Figs. 14, 15, 16, and 1S.

Vhen the handle S3 is in the position indicated by dotted lines in Fig. 1S, its slot 84 is in line with the `other slots last above mentioned, so that a thread may be passed through all said slots to a central position, and then by moving the handle 83 to the position shown in solid lines in Fig. 1S the thread is confined to a vertical movement through the slot S5 of the vertical shaft 62.

The rotation of the gear 56, derived, as al- IOO IIO

ready explained, from the shaft 39, (when the shipping-lever 46 has thrown the beveled.

gear 52 into engagement with the beveled l gear 45,)causes the'rotation of "thevertical shaft 62 and its standards 65'.' This rotation ot' the standards 6 5 causes the beveled gear 67, which is mounted therein, to move around the fixed-beveled gear 61, and the rotation of lthe shaft 66 f so caused compels the rotation it is properly twisted by said passage.,4 After leaving the twisting mechanism just desion-bars 90, v91,'aud 92are mounted on said brackets 87 88, and 8,9,.respectively, each scribed the thread next passes over atension device `shown in Figs. 1 and 10 and in enlarged detail in` Fig. 12 anddescribed as follows: Onthe frame 1.a plate 86is bolted,

'which has three long brackets'orarms'87, 88,'y and- 89, each'ending in a headwhich has an aperture rectangular, in 'crossfsectiom Tenhaving at vits outer end two grooved tensionwheels 93, rotatablymounted thereon, and eachftension-bar has a shankrectangular in cr0sssection, which is inserted adj ustably in said aperture of the head ofeach bracket, and `a set-screwholds the tension-bar in its adjusted position, therebyinsurin'ga regulated `1o. from the plate 86 between the longer bracktension'for the thread, which passes between thetension-rollers,as' shown in Figs. 1 and Intermediate short bracket-arms extend ets, as shown in Fig. 12. 'Each of these intermediate brackets has a head with an' aperturetherein like thosehereinbeforedescribed,

and tensionbars are mounted adj ustablytherein, each having two tension-rollers thereon, all as fully illustrated in Fig. 12. From this tensiondevice the thread next passes to a brushing device, shownin Figs. 1 and 10, and'in enlarged detail views in Figs. 22,23, 24, fand 25 and describedas follows: vOn the frame 1 are standards` 94 95, bolted thereto .andhaving tubular .bearings .96 97 on their upper ends. A shaft -98 has Sits two ends formed into pipes 99 100, respectively. At the. closed bottom of Veach of thesel pipes is a vent or' hole passing through' the side of the pipe,

as vplainly seen in Fig. 22. On the pipe 99 is mounted a'steamcylinder 101,having atubu larhub or extension 102, the exterior. surface of which in a portion thereofis in loose contact with the interior surl'acefotl the tubular bearing 97. The pulley 8 is also mounted fast upon the pipe 99. Q A steampipe 103 of the same diameter and bore-as the pipe- 99 is loosely inserted'in the end of the hubv or extension 102 ofthe steam-cylinder, audits inner end abuts the outer end of the pipe 99, as shown in Fig. 2 2. A stung-box104 surrounds the outer peripheral end of the `hub or :extension v102 and said pipe 103,' and -a coupling 105`unites.

th'epipe 103 toa steam-pipe 106. On' the open'- end of the steam-cylinder 101 is an out- -l wardly extending annular iaugez107', and abutting it and fastened thereto is a circular disk 108, having..acentralfaperture'to-allow` Y the passage of the'shaft98 through it. v This disk108 has an integral tubularhub 109, and onthe oppositeend of said tubular hub -1094 is another disk 110, integralwith it and having a central aperture for the `passage of the shaft 98 through it.4 A steam-cylinder 111 75 has an outwardly-extending annular'liange 112 bolted to the disk 110'and is'provided with a central aperture. The pulley Sabas a long tubular hub' 113, looselymounted on the pipe and passing through the central I aperture of the'cylinder 111, andsaid hub is supported by the tubular bearing 96 ofthe bracket 94.' A steam-pipe 114 is connected by'a'coupling 115 to a short pipe'116, whose inner end abuts the outer end of-.the pipe 100. Y l

Astufting-box 117 yis mounted on the pipe l 16, and a stuffing-box 118 is mounted on the hub 113 and is bolted to a central hub 119 of the cylinder 111. Four steampipesi120, 121, l 122, and123 are mounted rotatably in holes madethereforin the disks 108 and 110. *In

the cylinder 111 theserpipes have closed ends,

but are providedeach with a vent or'opening,

as seenV in Fig.22.

rThese disks 108 and 110 each have four tubular'projections *or bearings vfor the support ofsaid four steam-pipes 120,121, 122, and 123, aud-' stufling-boxes 124 are secured on said-hubs. Said four stea'm-` Ico having bristles -126 arranged in bunches, and

the end ofeach block 125 is concentrically tapered to receive a cap 127, as seen in Fig. 24..

On the end of `each off thepipes 120,121,

122, and 123 is a geal', those shownin Fig.'22'

being designated as 128 and;129, andthese four gears are driven by a central gear 130, lwhichA is fastened to the hub 113 of the pul- The belts v7 and 9,-passing over thel .pulleys 8 and 8,-cause the steam-cylinders 1 01fand 111to rotate, with their connected parts,'and

the vgear 130, rotating with the samespeed and in the same time, causes the rotation of the four gears on the steam-pipeshafts 120,

121, 122, and 123 withav greater speed,be vcause each ofthe said four gears is of a'less diameter than that ofthe central gear 130, which drives A them all'. Steam passingup through the pipe 105 goes throughv the pipes 103 and 99 into the `cylinder 101and thence n v passes through each of the pipe-shafts 120,

121, 122, and 123 andout ofthe vents thereof I `125 into the cylinder 111 and thence through the hole in the pipe 100,out through the pipe 116, ,and into and through 'the pipe 114. vFrom the brushes 125 the threadr passes through a l l tension' device exactly like that alreadyde` scribedand thence to the-ironing-cylinders,

which are shown in-Figs.1,10, and llandlj. in enlarged detailviews in Figs. 19, 20, and

21 and are described as follows: Thestearnpipe 105 is connected by a coupling (or elbow,

as the case may be) 131 to a short pipe 132. The pulley 11 is mounted on an extended hub 133 of a steam-cylinder 134. This hub 133 is supported in the bearing 135 of a bracket 136, which extendsfrom the frame 1. A shaft 137 has its two ends formed into pipes 138 139, each having a vent at the inner or closed end for the passage of steam therethrough. The cylinder 134 at its upper end has an out- Wardlylextending annular flange 140. The pipe 133 passes through a central aperture in the cylinder 134. A circular disk 141 has a central aperture for the passing of the shaft 137 through it and is fastened to the flange 140 by bolts, as seen in Fig. 19. The disk 141 has an integral tubular shaft 142, through which the shaft 137 passes, and at the opposite end of the tubular shaft 142 is an integral circular disk 143. A steam-cylinder 144, having an outwardly-extending annular flange, is bolted thereto and has a hub 145. The pulley 11n has a long extended hub 146, which extends into the cylinder 144, and said hub 146 is supported in the bearing 147 of the bracket 148, which extends from the frame 1. The hub 146 is mounted fast on the pipe 139. Ashort pipe 149 has its inner end abut the outer end of the pipe 139, and said pipe 149 is connected by a coupling (or elbow, as the case may be) 150 to the pipe 114. A stuifing-box 151 surrounds the pipe 149. A stuifing-box 152 surrounds the hub 139 and is connected to the hub 145 of the cylinder 144, and a stuffing-box 153 surrounds the pipe 132. On each of the disks 141 and 143 are six tubular hubs, and on each of these hubs there is a stuffing-box 154. There are six steam-pipes 155, 156, 157, 158, 159, and 160, mounted between the disks 141 and 143, which pass through the tubular bearings of said disks and through holes made in said disks for their passages. Each of these six pipes has an open end opening into the cylinder 134. The opposite ends ot' said six pipes are closed; but each has a vent opening into the cylinder 144. On each of these six pipes there is a gear 161, and all these are turned by a central gear 162, mounted on the extended hub 146 of the pulley 11, On each of these six pipe-shafts a series of ironers 163 is mounted and secured thereto by set-screws, as illustrated in Fig. 19. These ironers 163 have beveled peripheral surfaces. Collars 164 on the said shafts and secured in place by setscrews hold said ironers from lateral movement on their respective shafts. The belts 10 and 12, passing on the pulleys 11 and 11a, cause the steam-cylinders 134 and 144 to rotate with their connected parts, and the gear 146, rotating with the same speed and in the same time, causes the rotation of the six gears on the steam-pipe shafts 155, 156, 157, 158, 159, and with a greater speed, because each of the said six gears is of a less diameter than that of the central gear 146, which drives them all. Steam passing up through the pipe 105 enters through the pipes 132 and 138 into the cylinder 134, and thence passes through the pipes 155, 156, 157, 158, 159, and 160 and out through the vent-holes thereof into the cylinder 144, and thence through the opening in the pipe 139 out through the pipe 114. In Figs. 4, 5, and 6 Ishow modified forms of these ironers. In Fig. 4 the ironer is cylindrical, in Fig. 5 it hasa central V-shaped peripheral groove, and in Fig. 6 a long tube has such peripheral grooves at intervals. As shown in Fig. 11, the preferred form is the conical form hereinbefore described; but the ironers on one shaft are arranged in one direction, and those on the next shaft are arranged in the opposite direction, and this alternate arrangement is found to produce the most satisfactory results. From thisironingdevice the thread next passes up and through another tension device like that already explained, thence up through another ironing device like that already described, and thence up through anotherl tension device like that already described,`and thence up through another twisting device like that already described, all as shown in Fig. 10, and thence to a winding device (shown in Figs. 2, 3, 7, and 10,) Which Iwill now describe. A pulley 20, mounted upon a standard 2l on the top of the machine,is driven bya belt 19 from a pulley 18, as shown in Fig. 10. The pulley 2O rotates the shaft 165. This shaft has a number of whirls 166 thereon. It is mounted on bearings 167168 on standards 169 170 on the top of the frame of the machine. At the ends of the shaft are the beveled gears 171 and 172. A beveled gear 173 is mounted on a shaft 174, which is supported in bearings 175 of the standard 170, and at the ends of the shaft 174 are crankarms 176 177. A beveled gear 178 is mounted on a shaft 179, which is supported in bearings 180 181 of the standard 169, and at the ends of the shaft 179 are crank-arms 182 183. On a rail 184 are mounted spindles 185, which spindles are supported midway their length by the rail 186. Each spindle 185 has a Whirl 187, and a band or belt 188 from the whirls 166 to the whirls 187, respectively, rotates each spindle 185. Each spindle 185 carries a spool 189, loosely mounted thereon. erse-rail 190 has thread-eyes 191, and the thread passes from the upper twisters through the eyes 191 and is wound on the spool 189. The traverse-rail 190 has a guide-rod 192 bolted thereto at 193 on each end, which guide-rod 192 passes through a Vertical longitudinal opening 194 in a standard 195 at each end of the machine. A link 196 is loosely mounted on a block at the inner end of the rod 192 and is pivotally connected at its outer end to the crank-arm 17 7. Thus the rotation of the pulley 2O turns the shaft 165 and the beveled gears 171 172 thereon, and these heveled gears turn the beveled gears 173 178, which rotate their respective shafts 174 179 and carry around the crank-arms 177 183, re-

A trav- IOO IOS

ITO

I spectively. The crank-arm 177 is connected pivotally with the link 196, and as the crankarm 17,7` describes its -circle ,it forces by the link 196 the traverse-rail190 to alternately rise and descend, and thus the thread is wound regularlyupon the spools 189. 'A-

similarconstruction is at the other three connections of thetraverse-rails 190 and needs no description. The speed of the spooling can be controlled by cone-pulleys, as illustrated in Fig. ,7.

" By dividing the trough 24 into sections by` cross-partitions as many compartments may be made as desired, and in each compartment 4may be placedva different 'dye liquid, so that threads of different'colo'rscan be finished at the same time, and itis -evidentsaid trough i or itscompartments may be filled with liquiddyeor with liquid sizing, as may bepreferred. l 4 l The levers 28 enable the operator to immerse the thread in thedye liquor or sizing without soiling or wettingfhis hand.

By means of the shipping-lever 46 the twisting mechanism can be at anytime thrown into or out of engagement, andI each set or series of twisters is independent ofthe others.

The rollers 70 71 thoroughly Work the dye liquor or sizinginto the thread as it is being twisted. Bythe slot arrangement shown in Figs, let to 18, inclusive, itis apparent that the thread is easily inserted or taken out of 'the twisters, andihat `when a thread breaks or runs out itcan easily be tied and replaced whichthey are mounted enables the proper laying of the fibersfof the thread as the thread passes angularly, over each brush in turn, `as illustrated in FigAlO.

The steam heat in the brush-cylindersand in the brush-shafting enables the rapid drying `of the thread. I

In the ironingdevice the thread istsub-y jected to great heat `from the-steam which passes through the cylinders and pipes. Each.

ironer is hot, and Aeach row of ironers on a Vshaft revolves more rapidly than thesteamy -which standards have ahorizontal slot eir-` cylinders between which `saidironers and shafts are mounted. This rapid rotationof theironers gives the thread al high gloss and v vsuperior finish. By the conical-shape of the ironers andtheir alternatearrangement the.l

thread is finished round'and is not flattened, as might more or less be the case if the surfaces of the ironers were not inclined toeach4 other, as specified.. i l n lVIy improved machine is made ,much more Acompact than those ofy the same capacity, but otherwise constructed.

The mechanism is simple and easily operated. Y l I claim as a novel and useful invention and desire to secure by Letters Patent l.
